Research On Netizens' Negative Emotion Contagion And Simulation Under Network Group Emergencies

The frequent occurrence of network group emergencies doesn't only damage the stability of the network but also the real society.Under the situation of network group emergencies,if the netizens' negative emotion exists for a long time and can not be controlled,there will be bad behaviors induced by netizens,so it's an important task for some relevant departments to monitor the negative emotion and avoid emotional polarization of the netizens.At present,the scholars made many studies on negative emotion contagion in the real world.However,there are very few researches on netizens' negative emotion contagion under the network group emergencies.Trough the study of netizens' negative emotion under network group emergencies,we will obtain a theoretical basis for reducing the negative emotion harm to the network and real world.Firstly,we summarized researches on emotion and its transmission.Also,we introduced the related theories of netizens' negative emotion under network group emergencies.Secondly,we analyzed the transmission mechanism of netizens' negative emotion and summarized the media types and influencing factors under network group emergencies.According to the instability and regulation of emotion,we divided the netizens into four categories: calm state,explosive state,temporary stable state and stable state.And then the relationships of the four categories were discussed.Thirdly,based on the dynamic principle of infectious diseases,we established a netizens' negative emotion contagion model under network group emergencies by considering the characteristics of emotion and the effects of government.Then,we solved the model and got two kinds of equilibrium.Also we analyzed the stabilities of the two kinds of equilibrium and the internal mechanism of the propagation threshold.After that,we analyzed the influences of the propagation threshold on the negative emotion contagion through the simulation analysis.Finally,based on the model of netizens' negative contagion,we verified the reasonableness of the model and analyzed the different parameters' effects on netizens' negative emotion with a real case.And then some strategies were put forward according to the analysis.
